I'm info dumping some links about open-source robotics. The rabbit hole runs deep and this barely scratches the surface.

Disclaimer: I haven't tried any of these yet. Based on a cursory search and following links from the great Open-source robotics Wikipedia page.

Robotics simulation on Godot

• https://github.com/flynneva/godot_ros - Proof-of-concept integrating ROS2 (Robot Operating System) with Godot, for a 3D robot simulation environment. (Updated 8 months ago)

• https://github.com/nordstream3/Godot-4-ROS2-integration - A fork(?) of the above. The readme is clearer with visual examples of what it's meant for. (Updated 12 months ago)

• https://github.com/plaans/gobot-sim - A top-down 2D factory simulation of packages being processed by machines. (Updated 3 months ago)

• https://lab.nexedi.com/nexedi/godot-modbus-demo - Exposing a modbus interface to control simulated industrial components. (Updated 5 years ago.) Comes with a blog post which might be more recent (a year ago?).

• https://arxiv.org/abs/2412.18408 - "Exploring Flexible Scenario Generation in Godot Simulator" about generating simulated physical scenes for testing computer-controlled cars. Write-up only with no code. (Submitted 9 months ago)

Robotic car simulation on Unreal Engine and Unity

• https://github.com/carla-simulator/carla - "CARLA is an open-source simulator for autonomous driving research." They mostly target Unreal Engine. Regularly updated and popular with 13k stars on GitHub.

• https://github.com/microsoft/AirSim - Microsoft and IAMAI collaborated (plus DARPA funding?) to create an open source simulation platform for both flying drones and autonomous cars. Targets Unreal Engine and experimentally Unity also. Soon being sunset and replaced with a new project confusingly named "Project AirSim."

• https://github.com/iamaisim/ProjectAirSim - The successor to AirSim. The GitHub shows it's only at version 0.1.1 though.

Robot Operating System (ROS2)

• https://github.com/ros2/ros2

• https://docs.ros.org/en/kilted/Tutorials.html - Tutorials beginning with TurtleSim, a top-down 2D turtle scene where you control turtles. Looks like ROS2 uses familiar network messaging patterns like Publish-Subscribe.

• https://vimeo.com/osrfoundation/videos/sort:date - Presentation videos. Looks like the Open Robotics foundation just completed a developers' conference in Japan two days ago. The presentations from ROSCon JP are Japanese-language-only. Next one is coming very soon this October in Singapore.

How to get started?

That's a lot of links. I'd first figure out what I want to do. Humanoid robots seem popular lately—like the Berkeley 3d printed robot—so it'd be interesting to start there, although it doesn't map cleanly onto the projects I linked. So maybe if I imagined a robot with a human torso and arms, but with wheels and car-like locomotion. Then I could use a combination of the car simulators and probably ROS2 to deal with the upper body components? Or maybe there is another solution for the torso and arms that is a more direct fit than ROS2? Maybe iRobot/Roomba has a better solution for the car-like locomotion at this small scale?

Anyone used these before and have a story to share? Anyone curious to try one out and report back? I plan to, but no idea on my schedule.

Most of my professional work involves the plumbing side of things (e.g. APIs, integration etc.) So I've come to front end quite late, and dabbled in HTML/CSS/JS frameworks, and tried to create a thing or two using Python GUI frameworks too.

After spending a bit of time learning about game development in Godot, I decided it might be fun to try and build a simple desktop app in the engine, and it surprised me how easy it was, it took me a day or two to build a basic git front end.

Of course, if you ever need to build something outside of GDscript, it'll require building an extension, probably in C++, but it makes me wonder if those sorts of tools exist outside of games engines? It feels like game devs get a wonderful tool that they use as a garnish on top of the real work (the game).

I'd be keen to know what people who regularly build front end tools tend to prefer to use.

ETA: I just realized the title is a poor summary of what I'm actually asking about, sorry!

Hi,

I'm curious if anyone in this group has achieved success in game development, whether that's carving out a career or earning any amount of income from it.

I'm currently working as a software developer, but my passion lies in game development. I'm all too aware that achieving any measure of success in this field is next to impossible. Hence, I'm reaching out here, hoping to gather insights and advice from those who have walked this path in the past, or those who are currently walking alongside/behind me.

One of my specific questions is about the types of games I should focus on creating. Specifically, I've heard differing opinions on whether it's more advantageous to develop a series of small games with advertisements for mobile platforms or to invest in larger, premium games for platforms like Steam. Can anyone share their insights or experiences regarding this dilemma? Is there a clear advantage to one approach over the other?

Currently I am using godot to make a larger scale game, but I am considering switching to defold and making smaller scale games with ads.

I saw some folks here discuss making games for the playdate. How much should one consider targeting niche platforms like this? Some of the users I saw discuss this seem to have had good success.

Some general questions: How did you break into game dev? What were you doing before? Do you see game dev as a viable career, only as a source of side income, or is it just a hobby?

Any guidance or experiences you can share would be greatly appreciated.
